LAMP-EXTINGUISHER.

Specification of Letters Patent.

Patented Oct. 8, 1912.

Application filed. March 6, 1912. Serial No. 682,037.

To all whom 'it may concern:

Be it known that I, Mourns Scmmonn, a citizen of the United States ofAmerica, residing at McKeesport, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inLamp-Extinguishers, of which the following is a specification, referencebeing had therein to the accompanying drawing.

This invention relates to lamp extinguishers, and more particularly tothat type of lamp having a burner provided with a flat wick and has forits object to provide within the burner means in a manner as hereinafterset forth for snufling or extinguishing the flame of a wick when thelamp is accidentally tilted or upset thereby overcoming the liability ofconflagrations or explosions.

Further objects of this invention are to provide a lamp extinguishingmeans carried within the lamp burner and which is simple in itsconstruction and arrangement, strong, durable, eiticient and quick inits action, readily positioned within the burner and comparativelyinexpensive to manufacture.

With the foregoing and other objects in view the invention consists ofthe novel oonstruction, combination and arrangement of parts ashereinafter more specifically described and illustrated in theaccompanying drawing, wherein is shown the preferred embodiment of theinvention, but it is to be understood that changes, variations andmodifications can be resorted to which come within the scope of theclaims hereunto appended.

In the drawlngs wherein like reference characters denote correspondingparts throughout the several views :Figure 1 is a vertical sectionalview of a lamp burner showing the adaptation thereto of a flameextinguishing means in accordance with this invention. Fig. 2 is a topplan view illustrating the extinguishing means in an inoperativeposition, and Fig. 3 is a perspective view of one of the extinguishingshutters.

Referring to the drawings in detail 4 denotes a burner body havingmounted thereon a dome-shaped casing 5 formed with a transverse slot 6for the passage of the flame. The lower end of the casing 5 is seatedupon the burner body 4: and is provided with a lateral annular extension7 terminating in a vertically disposed annular flange 8, the lattertogether with the extension 7 and the lower end of the casing providesthe pocket for the lower end of the lamp shade. The shade is fixedlysecured in position through the medium of the upwardly disposedretaining tongues S) which project from the vertical flange 8. Theburner body is secured in any suitable manner to the neck of the oilreceptacle 10 of the lamp.

Projecting upwardly through the burner body t and arranged within thecasing 5 as well as being in alinement with the slot 6 is a wick tube 11provided with a wick 12. The tube 11 terminates a sufiicien-t distancefrom the top of the inner face of the casing 5 so that a clearance willbe provided to allow of the operation of the extinguishing shutters 13and 14.

The extinguishing shutters are oppositely disposed with respect to eachother, and when one is moved to extinguish the flame it is shifted in adirection toward the other. Each of the extinguishing shutters includesa body portion 15 having a flat arm 1.6 at each end, which are disposedat right angles with respect to the body portion 15. The arms 16 areconnected together at the top by a flat member 17 and by such anarrangement the upper portion of the shutter forms a pocket so that thesaid upper portion can be extended over the top of the wick tube tosnuff or extinguish the flame. The arms 16 of each shutter depend fromthe body portion 15 and have their lower ends aperturcd, as at 18 forthe passage of pivots 19, the latter being connected to the sides of thewick tube 11. The shutter 13 is of less length than the shutter 14 sothat the arms 16 of the shutter 1% will overlap the arms 16 of theshutter 13 when the arms of the shutters are mounted upon the pivots 19which is clearly illustrated in Fig. 1.

Means is arranged within the casing 5 for shifting the shutter 13 tosnuff or extinguish the flame when the lamp is tilted in one directionand for shifting the shutter 14 to snuff or extinguish the flame whenthe lamp is tilted in the opposite direction, normally the shutters arein an open position as indicated in Figs. 1 and 2, when the lamp is inan upright position due to the fact that the upper ends of the shuttersare heavier than the lower ends. The means for shifting the shutters 13and 14 consists of globular members 23 and 24 which are looselysuspended from their respective hangers 20 and 25, the latter beingfixed to and depending within the casing 7. The lower ends of saidhangers are provided with slots 21 and 26 respectively adapted for thereception of curved hooks 22 and 27 upon the upper ends of suspensionmembers 28, the latter having their lower ends fixed to the saidglobular members 23 and 24:. The hooks 22 and 27 are thereby looselyconnected to the lower ends of the hangers 20 and 25 respectively, sothat if the lamp tilts in a direction toward either of the shutters 13or 14, the globular member which is positioned in proximity thereto,will swing upon its hanger 20 or 25 and force its contiguous shutterover the wick tube 11 and thereby extinguish the flame.

The globular members 23 and 24 are freely suspended from the hangers sothat when the lamp is tilted either one of said globular members willact to shift the shutter to snufl or extinguish the flame.

What I claim is 1. An extinguisher for lamps comprising the combinationwith a lamp burner including a casing, a wick tube, and a pair ofoppositely movable shutters pivotally connected to the wick tube andcapable of being shifted over the tube to extinguish the flame,

of a pair of hangers connected to and depending in said casing, aglobular member arranged in proximity to each of said shutters, andsuspension members attached to said globular members and looselyconnected to said hangers whereby when the lamp is tilted one of saidmembers will move to shift a shutter to extinguish the flame.

2. An extinguisher for lamps comprising the combination with a lampburner including a casing, a wick tube, and a pair of oppositely movableshutters pivotally connected to the wick tube and capable of beingshiftedover the tube to extinguish the flame, of a pair of hangersconnected to and depending in said casing, a globular member arranged inproximity to each of said shutters, and suspension members attached attheir lower ends to said globular members and having hook-shaped upperends movably connected to the lower ends of said hangers whereby whenthe lamp is tilted one of said globular members will shift a shutter toextinguish the flame.

In testimony whereof I afiix my signature in the presence of twowitnesses.
